Who wins on what

Ranked by what users actually praise

Overall Impression

Sound quality and control are excellent for the price. Users highlight the relay-based step volume control for near-perfect channel balance over the device's life, very low noise floor, and strong output power. Multiple A/B comparisons found it hard to distinguish from pricier amps like the Asgard 3. XLR inputs help guard against ground loops even though the amp is not truly balanced internally, and build quality plus aesthetics drew consistent praise from commenters.

The 'balanced' labeling sparked real frustration among buyers. Several commenters point out the SH-9 is single-ended internally despite having XLR connectors, calling it a marketing trick that led buyers to cancel preorders or feel buyer's remorse. Some argue balanced-vs-unbalanced barely matters audibly outside long cable runs, but others feel deceived given the price and the expectation set by pairing it with a balanced SU-9 DAC.

Power specs and missing features drew mixed reactions. Some listeners cite third-party measurements suggesting real output power is lower than advertised, and a few feel it's overpriced relative to cheaper amps offering more power. The lack of RCA outputs for preamp use and no 12V trigger were noted as omissions, while the remote control was repeatedly called a rare and valuable convenience worth paying for.
